What are the chemcial differences between Glucose & Sucrose?

http://en.wikipedia.org/wiki/Sucrose


Sucrose (common name: table sugar, also called saccharose) is a disaccharide (glucose + fructose) with the molecular formula C12H22O11. Its systematic name is β-D-fructofuranosyl α-D-glucopyranoside. It is best known for its role in human nutrition.
Pure sucrose is most often prepared as a fine, colorless, odorless crystalline powder with a pleasing, sweet taste. Large crystals are sometimes precipitated from water solutions of sucrose onto a string (or other nucleation surface) to form rock candy, a confection.

Like other carbohydrates, sucrose has a hydrogen to oxygen ratio of 2:1. It consists of two monosaccharides, α-glucose and fructose, joined by a glycosidic bond between carbon atom 1 of the glucose unit and carbon atom 2 of the fructose unit.

Sucrose melts and decomposes at 186°C to form caramel, and when burnt produces carbon dioxide and water.



Glucose (Glc), a monosaccharide (or simple sugar), is one of the most important carbohydrates. The cell uses it as a source of energy and metabolic intermediate. Glucose is one of the main products of photosynthesis and starts cellular respiration. The natural form (D-glucose) is also referred to as dextrose, especially in the food industry. This article deals with the D-form of glucose

Answer 2

glucose is a monsacharide meaning there is only one sugar molecule present while sucrose is a disacharide. sucrose is made of gluclose and fructose (not too sure if it is fructose) combined together. glucose is easier to use because it doesn't need to be broken down unlike sucrose and the other di- and polysacharides

Answer 3

From wikipedia:

Simple sugars include sucrose, fructose, glucose, galactose, maltose, lactose and mannose. Disaccharides occur most commonly as sucrose (cane or beet sugar - made from one glucose and one fructose), lactose (milk sugar - made from one glucose and one galactose) and maltose (made of two glucoses). These disaccharides have the formula C12H22O11
